Patented July 1, 1941 PATENT OFFICE CABLE CONNECTOR 7 Arthur R. John,Dayton, Ohio I Application March 12, 1940, Serial No. 323,563

3 Claims. (01. 173-328) (Granted under the act of March 3, 1883, asamended April 30, 1928; 370 0. G. 757) The invention described hereinmay be manufactured and used by or for the Government for governmentalpurposes, without the payment to me of any royalty thereon.

This invention relates to a plug and jack for use in making anelectrical coupling between one or more sets of wires in circuit.

The invention more particularly relates to electrical connectors inwhich the mating connector elements are housed and shielded withinseparate complementary metallic shield members.

It is an object of this invention to provide a sealed plug which may bereadily assembled and disassembled without the use of special tools.

It is another object of this invention to provide a plug to which thecable wiring may be soldered prior to assembly.

It is another object of this invention to provide an electricalconnector which is dustprooi. and dampproof and which can be assembledand disassembled without twisting of the cables.

It is another object of this invention to provide an electricalconnector which not only permits ready inspection of the solder contactsbut also permits circuit and continuity tests-with the plug in partiallydisassembled condition but opera-e.

tively connected with the associated equipment. It is a further objectof this invention to profrom the rear end oi. the plug assembly; 7

Other objects of invention will become parent from the followingdescription taken in connection with the accompanying drawing:

Figure 1 is an elevational view of the assembled plus and lack; v

Figure 2 is an exploded perspective view of Figure 3 is an elevationalview of the inner sleeve member; I

Figure 4 is an end elevational view of the inner sleeve member showingthe ferrule-receiving slot;

Figure 5 is an elevational view of'the ferrule;

Figure 6 is a cross-sectional view of the ferrule taken along the lines6-6 of Figure 5'.

Referring to the drawing, the jack member is vide an assembly by whichthe cable wires and contact-sleeve retainercan be removed composed ofhousing I which contains male connector elements-referred to generallyas 1 l1.

These connector elements are suitably separated by insulating material(not shown) and have soldered thereto the wires of the cable referred togenerally as i8. Housing I is suitably fastened to plug housing 2 bycollar 3, threaded to correspend with threads on housing i. Collar 3 isloosely carried by housing 2 between flange 2i and rib 22. Plug 4,formed of suitable insulating material, is adapted to retain connectorelements generally referred to as 5. These connector elements havesoldered thereto at one end thereof the individual wires of the cableIS. The other ends of the connector elements are split for irictionallyreceiving connector elements 5, and resiliently held together by coilspring 20. Sleeve 6 is formed with a tubular plug-receiving portion 8and a longitudinal sectional portion 9 formed in the shape of a troughby cutting away part of the tube. This trough portion is somewhat longerthan the plug 4, so that the plug can be removed therefrom with thewires soldered to the connectors without breaking the solderedconnection. Plug 4 is suitably held in the tubular portion of sleeve 6by set screw 1. Sleeve 6 also has an end plate member i0 having a radialslot Ii therein for laterallyslidably receiving a ferrule-i2, solderedto cable IS. The

ferrule is provided with straight side portions.

i3 which cooperate with the sides of slotii to prevent rotation of theferrule when operatively positioned with respect to the sleeve 6." Theferrule is threaded at M to receive nut 15 which locks the sleeve to thehousing and seals the cable-receiving opening i6 in the housing.

In disassembling e, device, starting with the from housing 1.. Sinceextended relative movement between collar '3 andhousing 2 is preventedparts as shown in Figure 1. collar 3 is unscrewed by flange 23-cooperating with flange 2i and rim 22, rotation of collar 3 initiatesseparation of connectors l7 and 5. Complete separation is eflected bypulling housing I away from the plug assembly. Nut i5 is then unscrewedand-housing 2 slid alo'ngcable i9, uncovering sleeve 6. screw 1 is. thenremoved from tubular portion 8 or sleeve 8, ferrule i2 slid laterallyout of slot ii, and plug-4 slid longitudinally into space 9 of thesleeve 6. Contact plug 4, with the wires of the cable is solderedthereto, is then removable from inner sleeve 6' by lateral movementthereof.

When assembled, plug 4 is snugly received in and positioned by tubularportion 8 of sleeve 8. thereby firmly holding the connector-elements 5in position when forced into engagement with.

tion, taken in connection with the accompanying drawing, is by way ofillustration only, it being intended to limit the scope of the inventiononly by the appended claims.

I claim:

1. In a sealed cable connector of the type having a jack unit and asocket unit and means for sealingly connecting the units, one of thesaid units comprising: a housing having a cablereceiving openingtherein, a connector plug, a connector-plug-positioning sleeve having atrough portion of greater length than said connector plug, a tubularconnector-plug-receiving portion attached thereto at one end thereof anda radially slotted end portion attached to the other end thereof, acable, a cable-receiving ferrule positioned in the slot of said endportion and received in said cable-receiving opening, and means forsealingly connecting said ferrule and cable to said housing.

2. In a cable connector, an assembly including:

a housing; a sleeve member having a tubularportion, a radially slottedend portion, and a trough portion therebetween; a contact-retain plug ofless length than the length of said troug portion and operativelypositioned in said tllbl lar portion; a cable; a cable-receiving ferrulenon-rotatably received in the radial slot of said end portion; and meanssealingly connecting said ferrule and cable to said housing.

3. In a cable connector, an assembly including a housing; a sleevemember received in salil housing, said sleeve member including a tubularportion, a radially slotted end portion, and a trough portiontherebetween; a contact-retainer plug of less length than the length ofsaid troughportion and operatively positioned in said tubule r: portion;a cable; and cable-carrying means receivable in the radial slot of saidend portion for fastening said sleeve to said housing.
